A 0.08-7 GHz Low Power Low Noise Amplifier Design Using 0.18 μm CMOS Technology

Abstract

A design of wideband low noise amplifier here can be implemented using T-coil network as a high order filter for bandwidth extension. This technique is incorporated into the design of the input matching and output peaking networks of a low-noise amplifier. The intrinsic capacitances within the transistors are exploited as a part of the wideband structure to extend the bandwidth. Using the proposed topology, a wideband low-noise amplifier with a bandwidth of 0.08–7 GHz, a maximum gain of 18 dB and noise figure of 6 dB (min) is achieved. The total power consumption of the wideband low-noise amplifier from the 1.8Vpower supply is 4.5 mW. For design of this type of wideband low-noise amplifier 0.18 μm CMOS technology is used.
